This is the Shimano Ultegra Di2 Front Derailleur for braze-on mounting compatible frames. Our Ultegra Di2 series with electronic shifting is "pro-proven" as it is a direct trickle down from our Dura Ace group.

  • Programmed automatic trim function
  • The support bolt creates a rigid platform for the front derailleur to move the chain to the outer chainring
  • Keeps correct alignment, even when under high pedaling torque
  • Weight: 155g



A technological innovation of the computerized shifting system based on the DI2 concept with which is called, the SEIS (SHIMANO ELECTRONIC INTELLIGENT SYSTEM).
The SEIS innovative shift technology is still based on the SHIMANO INDEX SYSTEM (SIS) that has proved its superior gear changing characteristics over the years. The big difference is that in this case, the shifting action is provided for by electronics instead of mechanics.
This electronic shifting system has been extensively tested over past two years by several professional riders in all conditions possible, such as rain, mud, low temperatures, cobble stone roads and combinations of all of these at the same time.
Shifting is executed by simply pressing the button.
No power is needed to shift, which gives important advantages since it is easier now to always keep a tight grip on the handlebar and to keep your concentration on riding instead on shifting.
The shift system allows accurate and effortless shifting in difficult circumstances for example when you have cold hands or when you are completely exhausted. Furthermore, the shifting performance will never be affected by contaminated or stretched cables since the shifting signal is transferred electronically. The operating buttons work similarly to mechanical DUAL CONTROL LEVER so you don’t need to re-program your mind for the SEIS.




The E-TUBE platform's “Plug & play” and D-FLY wireless connections make it easier than ever to check the system's status, and apply customized settings to DI2 and SHIMANO STEPS components with a PC, tablet or smart phone.
